Gaming's most influential FPS celebrates its 20th birthday

Released in 1992, the game gave rise to a fledgling studio of plucky young upstarts called id software, who later went on to make a little game called Doom. (Perhaps you've heard of it?) While that game is perhaps the better known of the two, Wolfenstein 3D is considered the birth of the genre that continues to be the cornerstone of gaming to this day.

To mark the occasion, Bethesda is giving away the entire iOS version of Wolfenstein 3D for the princely sum of naught. Ziltch. Free. Go ahead, download the entire game right now and shoot Nazis on the bus. Don't have an iDevice? No problem, just head here to play the game in your web browser. Everybody wins!

Also, be sure to check out Bethesda's special video podcast, which sees John Carmack revisiting the game and explaining the design process. It's an insightful watch.

Question is, does Wolfenstein 3D still hold up today? Or is merely a dusty digital relic? Let us know in the comments.
